-## Example Usage with Collaborative Custom Property Management
-
-The following example illustrates collaborative management of repository custom properties by setting `exclusive_custom_properties = false` and delegating an additional property to the standalone `github_repository_custom_property` resource.
-
-```terraform
-# This example demonstrates collaborative management of repository custom properties.
-# It assumes the organization already defines the referenced custom properties.
-
-resource "github_repository" "example" {
-  name        = "example-shared-custom-props"
-  description = "Repository with collaboratively managed custom properties"
-
-  exclusive_custom_properties = false
-
-  custom_property {
-    name  = "deployment-environment"
-    value = ["production"]
-  }
-}
-
-resource "github_repository_custom_property" "compliance" {
-  repository     = github_repository.example.name
-  property_name  = "compliance-tier"
-  property_type  = "string"
-  property_value = ["regulated"]
